SPECIFICATION forming part of Letters latent No. 694,580, dated March 4, 1902.

Application filed August 17, 1901. Serial No. 72,440. (No model.)

To aZZ whom, it may concern:

Be it known that I, ERNEST LEsLIE RAN SOME, a citizen of the United States, residing at New York, in the State of New York, have invented an Improvement in Concrete Construction, of which the following is a full, clear, and exact description.

My invention relates to-the construction of buildings of reinforced concrete; and it consists in the extension of areinforced concrete floor over the external piers or walls of a building and in the formation of this extension into an exterior belt course, and when the floor rests upon external piers it further consists in integrally combining with the floor beam-like extensions above and below to carry the floor from pier to pier and at the same time to form the window-heads or curtainwalls terminating in window-heads for the story below and the window-sills or curtainwalls terminating in window-sills for the story above.

The accompanying drawing illustrates my invention, in which- Figure l is a front exterior view of the floor with its extensions. Fig. 2 is a cross-section of the same on line X X, and Fig. 3 is a crosssection of floor resting on a wall.

I carry out my invention as-follows: After the wall or piers have been brought to the required height the molds for the floor are set in place, and the floor is extended over the wall or piers and molded into a belt course A, as in Figs. 2 and 3.

downward extension B, which extends to the "windows 0, of which it forms the head, and

extension is made of one integral piece with the floor bymeans of the coil-joint H or'other suitable union, and it extends upward to the window K, of which it is the sill. It is by When thefioor A has to rest upon piers, it is made with the.

Between the piers it can be reduced to preference rabbeted into the piers. The advantages of this floor are, first, it thoroughly binds the building together, extending as it does entirely across the walls and piers; second, it afiords an architectural feature at a trivial cost, third, by the downward extension a deep beam is formed for supporting the floorload, while it also fulfils allthe functions of a window-head and curtain-wall; fourth, by the upward extension'the depth of the beam is further increased and extended from Y to Y,
